How to file for divorce in Lyon County

The steps below apply to most uncontested divorces in Iowa. Contested cases or those involving complex assets, business interests, or child custody disputes may require additional steps and professional legal guidance.

Confirm you meet the residency requirement. Iowa requires that at least one spouse has lived in the state for the required period before filing. Check the Iowa courts website for the current residency requirement.
Choose your divorce type. Most states offer an uncontested (agreed) divorce path when both spouses agree on all terms — property division, child custody, child support, and spousal support. If you disagree on any issue, the case is contested and may require mediation or a court hearing.
Obtain and complete the required forms. Download the official divorce petition and related forms from the Iowa courts website. Fill out all required documents carefully and have them signed and notarized where required.
File your documents with the clerk. E-file (recommended): Use the e-filing portal to submit your documents online and pay the filing fee by card. In person: Bring copies of all completed forms to the Lyon County Clerk of Courts.
Serve your spouse. If you are not filing jointly, your spouse must be formally served with the divorce papers. Common methods include: waiver of service (if your spouse agrees), sheriff or constable service, a licensed process server, or service by publication if your spouse cannot be located.
Exchange financial disclosures. Most states require both parties to exchange financial disclosure documents — typically including tax returns, pay stubs, bank statements, and documentation of assets and debts. Check Iowa family law rules for the specific requirements and deadlines.
Attend mediation if required. Some counties require mediation before a contested hearing. Even if not required, mediation can help resolve disputes more quickly and affordably than going to trial.
Attend your final hearing. For uncontested divorces, the hearing is typically brief. Bring your completed final judgment form for the judge to review and sign. Once entered, the Final Judgment of Divorce legally ends your marriage.
